eovnnnon REMOTE-CO1TTROL STRUCTURE FOR VALVES Application filedSeptember 27, 1927. Serial No. 222,329.

The object of my inventionis to provide a remote control structure forvalves employing a float actuated member for contracting and expanding abellows containing liquid and connected by a tube with another bellowscontaining liquid, from which second bellows the valve is actuated.

lVith this and other objects in View, my invention consists in theconstruction, arrangement and combination of the parts of mg remotecontrol structure for valves,- W er eby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings,- in which:

Figure 1 is a side elevation of an installation embodying my invention,parts being shown in section and parts being broken away. I 1

Figure 2 is a detail, sectional view taken on the line 2-2 of Figure 1;and

Figure 3 is a similar view taken on the line 3-3 of Figure 1.

In the accompanying drawings, I have used the reference numeral 10 toindicate that portion of a tank shown. The tank contains a liquid 12,which may be oil or otherwise.

Extending. away from the lower part of the tank is a fluid conductingpipe 14 in which is interposed a valve 16 having a stem 18 projectingfrom the valve casing 20.

Supported on the tank is a float casing 22, the interior of which isconnected with the tank 10-above and below the casing by means ofsuitable pipes 24 and 26.

Supported on and extending away from the float casing 22 is a hollowcone-shaped float arm receiving member .28. Suitably mounted in the wallor walls of the member 28 is a shaft 30, which extends from the interiorof the member 28 to a point outside thereof.

In the float casing 22 is a suitable float 32, having the arm 34 fixedto the shaft 30 inside the member 28. As the liquid in the float casingrises or lowers, the float is raised or lowered.

Fixed to the shaft 30 outside the member 28 is a rod 36 on which is acounterweight 38.

- cated generally at B in Figu Fixed to the shaft 30 is a short arm 40to which is pivoted a link or rod 42. 3 Supported for instance on theflange 44 of the member 28, which is bolted to'the flange 46 of themember 22, is a plate or bracket 48. Secured to the plate or bracket 48is a casing 50, best shown perhaps in Figure 2.

Received within the casing '50 is a liquid containing bellows, indicatedgenerally at A, comprising a base member 52, having projecting therefroma tubular extension 54, the outer end of which is reduced andscrewthreaded as at 54*. The member 54 pro jects through the plate 48.

The member 54 has a bore extending therethrough, .which is enlarged atits outer portion to receivethe end of a liquid conducting pipe or tube56. The pipe 56 is secured to the reduced portion 54 of the extension 54by means of a compression fitting, indire 2. Thebellows A hasv what maybe called a top member 58 spaced fromthe base 52 and connected therewithby an annular, corrugated expansible wall 60.

Extending inwardly from around the bore of the extension 54 andprojecting from the base 52 is a tubular member 62. Extending inwardlfrom the top member 58 is a small-- er tubufar member 64, slidablyreceived in the tubular extension 62 and with it forming a suitableguide for the bellows.

In the tubular guide member 62 adjacent to the base 52-are suitableholes 66.

When the bellows is contracted, the liquid 68 therein is forcedoutwardly through the member. 54 and into and through the tube Mountedon the' valve casing 20 above mentioned is the central portion of 3,rectangular yoke or supporting bracket 70. A

second bellows indicated generall at C is supported on the upper portionof the yoke 70. The second bellows has the base .72

similar in construction to the base 52, a top 74 similar to thetop 58,the connecting wall 76 similar to the wall 60, an extension 78 similarto the extension 54, and tubes 80 and 82 similar to the tubes 62 and 64.

The tube 56 is connected withthe exten- 4 'g i on 78 bya compressionfitting B similar that alread described.

Extending rom the-top'74 of the bellows I C is a post 84, to which thevalve stem 18 is adjustably connected.

A protecting casing 86 is provided for the bellows C.

In the practical! operation of my improved Thus the expansion andcontraction of thei bellows A results in the contraction and ex pansionof the bellows C. The contraction and expansion of the bellows Creciprocates the valve stem 18 for thus automatically controlling thevalve 16 for allowing liquid,

' in excess of a given levl, to either flow, or

56, a structure 0 be drawn, from the tank 10. Inan installation where itis desired to supply fluid to the tank 10 and keep it at a predeterminedlevel, the arm 40 may be reversed for contively' connected. with saidstem, and a tube I connectingthe interior of said'bellows with eachother whereb the contraction or expans onof one bel ows serves to causeexpanslon or contraction of the other'bellows.

3.'In a device of the class described, a float cage, a shaft projectingtherefrom, a float in said cage havin an arm fixed to said shaft, an armon sai i shaft outside the float cage, a link pivoted to said am, aliquid receiving bellows having one end fixedly mounted and the otherend operatively connected with said link, a valve casing, a valvetherein having a stem projecting through said casing, a supportingeyokeonsaid casing, a liquid recelving lows having one end fixed to said yokeand the other end operatively connected with vsaid stem, and atubeconnecting the interiors of said bellows. 2
